ATHENS, Greece --- A defense company, a MEMS maker and a start-up RF specialist company are set to benefit from a three-year European collaborative research project called WIDE-RF. In particular, a radio frequency inductance modeling tool from Greek start-up Helic SA is being honed for market readiness in the near future.
A large consortium of European companies and universities are half way through the 36-month project to develop CMOS-compatible RF MEMS processes and devices, along with efficient electromechanical models and simulation methodologies.
The total budget of the project is 2.5 million euros (about $2.9 million) and the contribution from the European Union is less than $1 million (about 850,000 euro) a source close to the project said.
The participants include: Thales Airborne Systems (Paris, France) as the system-level user of the technology, TRONIC'S Microsystems (Grenoble, France) as the MEMS foundry and Athens-based Helic is providing design and modeling expertise. The Swiss Federal Institute of Technology of Lausanne - EPFL (Switzerland), the University of Cambridge (UK) and the National Polytechnic Institute of Grenoble - LPCS (France) are also contributing research to the WIDE-RF project.
Under conventional European collaborative research rules commercial companies can receive 50 percent of their costs in such projects while academic institutions can receive up to 75 percent of their costs.
The project is intended to ease the penetration of micro-machined structures in wireless systems for commercial applications such as cellular telephony and WLAN, as well as aviation and satellite electronics.
The partners' efforts are focussed on developing design and fabrication methodologies for MEMS devices such as RF switches and tunable inductors and capacitors that can be applied in reconfigurable RFIC and microsystems architectures across a range of frequencies spanning 800-MHz to 10-GHz.
The developed devices, when they emerge, should be applicable to tunable RF filters, wideband voltage-controlled oscillators and delay-lines for smart antenna arrays.
One expected outcome of the project is the production of a WIDE-RF library of electronic models for MEMS fabricated high-Q inductors, capacitive switches, and tunable elements that would be compatible with commercial circuit simulators and EDA frameworks.
On the reliability front, the consortium expects to deliver studies on the environmental and operational limits of RF MEMS components, and resolve some severe reliability issues inherent in some of them.
"A large effort in the WIDE-RF project is put on developing innovative wafer level packaging solutions inspired from TRONIC'S Microsystems patented technology used for custom accelerometers. Such packaging should limit the creation of parasitic capacitance. As the MEMS manufacturing expert, TRONIC'S Microsystems will ensure the manufacturability of the solutions and is ready to industrialize and produce the future wideband RF devices that will be the outcome of this common work," said Marjorie Trzmiel, RF MEMS project leader at TRONIC'S Microsystems, in a statement.
"Helic will be enhancing its RFIC inductance modeling platform with MEMS-specific options and act as the focal point for library build-up. We see significant long-term benefits in our multi-mode RFIC development activity, as well as our EDA activity which is now starting up," added Sotiris Bantas vice president of technology at Helic, in the same statement.
However while some of the MEMS intellectual property expected to come from the project will not be ready for a further 18 months, the RFIC inductance modeling platform, including the MEMS capability, is believed to be more or less ready now.
Helic was founded by engineers from the National Technical University of Athens in May 2000.

10 CEOs out in 2009:
It's been a tough year for the global electronics industry and CEOs. We survey the dismissal of 10 industry CEOs during the first three quarters of 2009 and what's ahead for the rest of the year.
Executive pay:
The economy stinks. Rank-and-file engineers are feeling the pain. What about technology CEOs? We crunched the numbers buried in corporate financial statements to find out. Here's what we found.
10 companies in trouble (revisited):
What follows is an updated version of 10 companies in trouble. Some companies have been removed since the last version, others remain. Still others have been added to the mix.
Early predictions for 2010:
The electronics industry is recovering, but there is still some uncertainty in the market. Some see a boom year in 2010. Some see a double dip. So what's in store for the rest of this year and 2010?
Top 10 IC vendors with cash:
The world's biggest IC companies by revenue rank not only among the best in their respective industry segments but are also more likely to have huge piles of cash that can be used to fund acquisitions, R&D and product development.
Notable women in microelectronics:
There is no better time than a global economic recession to examine the keys to successful corporate governance. So, EE Times has compiled an international list that celebrates women who are business and technology leaders in semis.
EE Times updates Silicon 60:
Seventeen companies have been added to the lastest version of our Silicon 60 list of emerging startups. Forty-three companies survived as emerging companies that are still worth watching.
